This is a neat little item. It is a blacklight/flashlight combination. Where blacklighting is not the end all be all in detecting fakes, it is a tool that can be used. Along with your knowledge of a piece, it may help you determine an authentic item from a fake. It works on cloth items and paper. If an item glows (or would fluoresce) under the blacklight, it may mean you want to research it further prior to purchase. This is a handy compact item that you can take to shows with you. It measures 6 3/8 inches in length by 2 1/8 inches in width and is only 3/4 of an inch thick. That means it would stow away easily in a coat pocket. It operates as a blacklight or flashlight using 4 AA batteries which are not included.
